The polytope-collision problem

Abstract:

The Orbit Problem consists of determining, given a matrix $A\in\mathbb{R}^{d\times d}$ and vectors $x,y\in \mathbb{R}^d$, whether there exists $n\in \mathbb{N}$ such that $A^n=y$. This problem was shown to be decidable in a seminal work of Kannan and Lipton in the 1980s. Subsequently, Kannan and Lipton noted that the Orbit Problem becomes considerably harder when the target $y$ is replaced with a subspace of $\mathbb{R}^d$. Recently, it was shown that the problem is decidable for vector-space...
